The house will be built in Dorking, England and everything that can be made out of Legos will be made out of Lego. Said May, "I've got a man working on a flushing Lego lavatory. We think it's possible." Seeing that Legoland doesn't even have a house made of Lego – and certainly not Lego toilets – this should indeed be a "pioneering Lego cause." So far, three million Lego bricks have been contributed to the build, but May is looking for more in case you have any lying around.
